Explanation:

To determine the densest form of matter, we analyze the particle arrangement:

• Solids: Particles are closely packed in a fixed, ordered structure with minimal intermolecular space. This tight packing leads to high mass per unit volume (density).
• Liquids: Particles are closer than in gases but more loosely packed than in solids, so density is lower than solids (in most cases).
• Gases: Particles are widely spaced with large intermolecular distances, resulting in very low density.
• Option A is incorrect because the three states have different densities. Option B (liquid) and C (gas) are less dense than solids in general. Thus, solids are usually the densest.

Answer:

D. Solid
